Simpack - How to get results by using 104: Spr-Damp nonlin Hysts Cmp in Simpack 2020

Hello everyone.

I am using 104: Spr-Damp nonlin Hysts Cmp in Simpack 2020 for modeling SL-76 draft gear used in freight trains by providing upper and lower envelopes as an input function.

However, after running the model for several hours (more than 24 hours),  the solver got stuck after a particular time (in my case, at 0.105 secs).

Can anyone suggest any method to solve this problem??

Thank you!!
